Project 220 is a unique ‘Best of’ list. Why? Using a 30,000 song sample, we determined the proportion of songs that each letter of the alphabet is… Each letter is allotted a number of spots on our list based on our sample. 4.5% of that sample had the letter ‘A’ as the first item in the song title, subsequently ‘A’ was allotted 9 spots on our list. Get it? No? Oh well.

Somewhere throughout our process we decided doing only one list for the all music ever was nearly impossible. So, we split the list into two.
